FLUOOSH!
As Elayne prepared a small meal to eat with Blackie and Rose, she absorbed Gustaf's enormous Magic Crystal. It had so much Mana that even after having been shattered, it held an immense power. If she were to absorb it all, wouldn't it feel like a slight waste?
Such a powerful Magic Crystal could also be used to make quite the wonderful equipment. The thing is, Elayne didn't seem to care, she was easily predicting only edgy-looking items would come out of fusing it with other equipment.
However, much like an enormous meal, she was unable to eat it entirely, and had to devour it by small bites slowly. Nonetheless, she was feeling slightly greedy, and only left a few smaller fragments, she used one of these fragments each for the three skeleton's evolutions, left a big chunk for Blackie to eat when he were to wake up, and then the other for Rose.
